Abstract
A wireless local area network includes a plurality of stations each comprising a data processing machine connected to a radio send-receive interface. Each data processing machine includes an interface controller for sending a message containing an address designating a destination station and for receiving messages addressed to it. The network further includes a repeater including a radio send-receive interface connected to a radiating cable passing near all the stations to receive all messages sent by the stations, to modify these messages to indicate that the message has passed through the repeater and to retransmit these messages over the radiating cable. The radio send-receive interface of each station ignores any messages not sent by the repeater. The wireless local area network finds an application in computer networking.
